A video editing system and method of computer system disclose at least one play mark and at least one leap mark by a mark unit to mark a complete frame of video data provided by a display unit, moreover, through a P frame differential value provided by a detect unit which is read by a video capture unit, it captures a complete frame which is marked as a play mark and a P and a B frame which are related to the complete frame and not less than the P frame differential value. By the setting of the leap mark, it will save the times of forwarding and efficiently shorten the delayed time caused by the forwarding function; and after that, generates a smaller file through code conversion of the video data captured by the video capture unit with a transformed unit.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A video editing system of a computer system, comprising: a display unit for receiving decoded video signals and then displaying a series of frames of the decoded video signals; a mark unit for providing at least one playback mark and at least one leap mark for respectively setting which frame of the frames of the decoded video signals is to playback and which frame of the frames of the decoded video signals is not to playback; a video capture unit for continuously and automatically capturing the frame which is marked with the playback mark and discarding the frame which is marked with the leap mark; said frame including I, P, and B frames, wherein said capture unit captures only those P frames having a data variation value from a preceding P frame greater than a pre-determined differential value of the P frame; and a transform unit for receiving, encoding and compressing at least one frame which is marked with the playback mark from said video capture unit, then transforming the at least one frame into a single file.
2. The video editing system of computer system of claim 1 , wherein said decoded video signals are compatible with MPEG format.
3. The video editing system of computer system of claim 1 , wherein said mark unit further comprises a mark index table for recording the physical storage location of the frame marked with the playback mark.
4. The video editing system of computer system of claim 1 , wherein said video editing system further comprises a decode unit for receiving at least one encoded video signal, then decoding said encoded video signals into said decoded video signal.
5. The video editing system of computer system of claim 4 , wherein said encoded video signal is compatible with MPEG format.
6. The video editing system of computer system of claim 1 , wherein said video editing system further comprises an input unit for providing at least one setting of said playback mark and said leap mark.
7. The video editing system of computer system of claim 1 , wherein said video editing system further comprises a detect unit for checking a different rate of adjacent frames which are marked with the playback mark.
8. The video editing system of computer system of claim 7 , wherein said video capture unit discards the adjacent frames detected by the detect unit, which are marked with the playback mark, having a different rate.
9. The video editing system of computer system of claim 1 , wherein said video editing system further comprises a storage unit for storing the frame captured by the video capture unit.
10. The video editing system of computer system of claim 1 , wherein said single file is an animation file.
11. The video editing system of computer system of claim 10 , wherein said animation file is compatible with JPEG format.
12. The video editing system of computer system of claim 10 , wherein said animation file is compatible with GIF format.
13. A video editing method of a computer system, comprising: (a) receiving decoded video signals and then displaying a series of frames of the decoded video signals; (b) providing at least one playback mark and at least one leap mark from a mark unit for respectively setting which frame of the frames of the decoded video signals is to playback and which frame of the frames of the decoded video signals is not to playback; (c) capturing the frame which is marked with the playback mark and discarding the frame which is marked with the leap mark; wherein said frame includes I, P, and B frames, and wherein the step of capturing includes only those P frames having a data variation value from a preceding P frame greater than a pre-determined differential value of the P frame; and (d) receiving, encoding and compressing at least one frame which is marked with the playback mark, then transforming the at least one frame into a single file.
14. The method of claim 13 , wherein said decoded video signals are compatible with MPEG format.
15. The method of claim 13 , wherein said mark unit further comprises a mark index table for recording the physical storage location of the frame marked with the playback mark.
16. The method of claim 13 , wherein before step (a) further comprises a step of receiving at least one encoded video signal, then decoding said encoded video signals into said decoded video signal.
17. The method of claim 16 , wherein said encoded video signal is compatible with MPEG format.
18. The method of claim 13 , wherein said mark unit is provided by an input device.
19. The method of claim 13 , wherein before step (d) further comprises a step (cl) of checking a different rate of adjacent frames which are marked with the playback mark.
20. The method of claim 19 , wherein the adjacent frames detected by the detect unit, which are marked with the playback mark, having a different rate, are discarded.
21. The method of claim 13 , wherein the step (c) further comprises a step (c 2 ) for storing the frame captured.
22. The method of claim 13 , wherein said single file is an animation file.
23. The method of claim 22 , wherein said animation file is compatible with JPEG format.
24. The method of claim 22 , wherein said animation file is compatible with GIF format.
